Maybe I don't write because I'm afraid to challenge the validity of my beliefs. Often, in writing, I find flaws in my reasoning.
So I avoid it entirely. I hide my irrationality from myself. Maybe that is why others don't write. They find their scripts not only aesthetically distasteful (ungrammatical and drole) but also illogical. They wake up the next day and ask, "who wrote this nonsensical drivel?"
Me? No. I dare not pick up the quill.
